cutting an image in a round saw blade

[Spyglass66]

Hello,
First post here so be gentle. I want to cut a design into a large round saw blade. Is it possible to set the X zero and Y zero to the center of the blade so that the design is perfectly centered. So far my experience has been cutting square plate and using the bottom lower left corner as the zero reference. I am hoping that there is a setting in the Sheetcam software that can change the Job layout.

Thanks for any help

I believe I figured it out. When you load your svg into Sheetcam there is an orientation square with a set of circles where you can select your zero reference position. What do they say about answers staring you in the face / hiding in plain sight. Great to be a newbie.
